Closed String Tachyons, Non-Supersymmetric Orbifolds and Generalised McKay Correspondence
Abstract
We study closed string tachyon condensation on general non-supersymmetric orbifolds of C2. Extending previous analyses on Abelian cases, we present the classification of quotients by discrete finite subgroups of GL(2; C) as well as the generalised Hirzebruch-Jung continued fractions associated with the resolution data. Furthermore, we discuss the intimate connexions with certain generalised versions of the McKay Correspondence.
